On the International Space Station many of the Earth’s environmental support systems have already been engineered. Examining how some of these key technologies work, allows us to understand the vital ingredients that make Earth such an ideal place to live.
In the video we explore how ESA is dealing with these scientific and technological challenges, and we answer questions like: Why do we need water and oxygen? How do astronauts get the oxygen they need to survive in space?

Feeding our future – nutrition on Earth and in space

The video illustrates how our bodies process food as a source of energy and building materials: what it importance of good nutrition for a healthy life and what can happen without it, whether here on Earth or in space? It looks at research for preserving and growing food for long flights, as well as valuable technology for future food supplies on Earth, where climate change and population growth are global challenges. New techniques developed for space missions can help to feed hungry people on our planet.
